Frequently Asked Questions

Who is running this study?
Greg Marcus, MD, MAS
and
José Sanchez, MD
are the principle investigators for the mRhythm study,
with contributions from many people from the Health eHeart team: Ricardo Barerra, Alex Cabrera, Rachel Gladstone, Ben Hobson, Carol Maguire, Todd Parsnik, Greg Marcus, Madelena Ng, Jeff Olgin, Mark Pletcher, José Sanchez, Cathy Stolitzka, Geoff Tison, and Jairo Vazquez.
The study is in partnership
with Johnson Hsieh and Brandon Ballinger at Cardiogram, who are building the
Apple Watch app
and machine learning algorithm.

What will participants have to do?
It's easy! Just download Cardiogram and sign up online for the mRhythm Study.
You'll be asked to complete surveys with your medical history. If you have
an arrhythmia and an AliveCor, you'll also be asked to link your AliveCor.
(If you don't have an AliveCor, we may have a limited number to send to you.)

When will results be published?
We hope to submit results to peer-reviewed journals by the end of 2016, and will be giving talks at places
like Strata 2016 to give progress updates before then.

If I have atrial fibrillation, can you treat me?
By law, a research study like ours cannot provide medical treatment. If the research proves successful,
we intend to apply for FDA approval and make our technology available to everyone.

What if I have more questions?
